In part II of this study, comparisons of some tribological parameters are made for specimens coated with titanium nitride as the top layer, but using different materials as the underlayer. For the specimens coated by the cathodic arc plasma deposition method, electroless nickel films of various thicknesses were deposited as the underlayer. For the specimens coated by the cathodic arc ion plating method, a titanium film with various thicknesses was deposited as the underlayer. The tribological performances of the two kinds of coating specimens were compared for the following parameters: wear rate, friction coefficient, adhesive strength, the effect of sliding speed on both the friction coefficient and wear rate, specimen's hardness and coating method. The role of the thickness of the two different coating layers, and of the material of the underlayer on the friction and wear behavior was investigated.
